Problems reburning flash chips

Anyone else here have to burn a flash chip 2-3 times(average) to get it to take? The 1st time it gets to the end 7F(something) and before it finishes I get a chip did not program error. It eventually take and works perfect. Any tips??

Thanks

Chris

Try programming it with a .bin of all FFs.
That's always worked for me.

Erasing the device should set the whole chip to FF. There may be a bug (Programmer) if you just re-program without erasing first.

That's exactly what mine does. I did fill the buffer with FF and program it from there a couple times. But that always took 6 tries. Not I just program right to it and it takes 2-3 times.

If you are talking about 29C256 like I'm using, you don't get the erase option for that in the Transtronics programmer.
